Hello, how can I install node-red-contrib-iiot-opcua using docker? Before I installed it only using the command npm install node-red-contrib-iiot-opcua, I tried to install it using the node-red palette but node not found.

Hi All

 

Seems like I'm a bit late to the thread, but if anyone has the same problem.

I've an prebuild image with opc-ua nodes in it.

use :

balena-engine run -it -p 1880:1880 --name nodered --restart always pxcbe/node-red:opcua

 

Kind regards

Hi,

 

wenn you try to install something via the node-red palette and it does not find any nodes, then probably the container does not have access to the internet. I had the same issue.

In my case the firewall settings were incorrect. Please also check the github repository. There is a workaround for firmware version 2020.6 to disable the firewall.
